Tree format requires Gradle 7.4 or higher

Hi team!

I wanted to play around with the tree format described in the README and came across the following error:

java.lang.NoClassDefFoundError: org/gradle/configurationcache/extensions/CharSequenceExtensionsKt
	at com.dropbox.gradle.plugins.dependencyguard.internal.DependencyTreeDiffTaskNames.createDependencyTreeTaskNameForConfiguration(DependencyTreeDiffTaskNames.kt:8)
	at com.dropbox.gradle.plugins.dependencyguard.DependencyGuardPlugin$registerTreeDiffTasks$1.execute(DependencyGuardPlugin.kt:108)
	at com.dropbox.gradle.plugins.dependencyguard.DependencyGuardPlugin$registerTreeDiffTasks$1.execute(DependencyGuardPlugin.kt:16)

I'm using version 0.3.0 of the plugin with Gradle 7.2 in our project.

I think this is because it relies on the CharSequence.capitalized() extension defined in /src/main/kotlin/org/gradle/configurationcache/extensions/CharSequenceExtensions.kt which only landed in Gradle 7.4.

Perhaps a small update to the README to point this out might be useful? Alternatively there is probably a Kotlin extension that does something similar?

Cheers.

Interesting. Thanks for calling this out. If it's an easy if/else I'm happy to take a fix. Otherwise, I think 7.4+ for this option seems reasonable. (since it's non-default)

Thoughts?

I downgraded to 7.2 and am able to replicate:

Sorry, I'm late picking up these messages. Yup, I'm in full agreement with your PR fix.

Many thanks for the quick turn around ☺️.
